NTI AUDIO/HD VIDEO MATRIX SWITCH
INTRODUCTION
The VEEMUX SM-8X4-HDA (VEEMUX-A) is a versatile multi-input audio/video matrix switch that independently switches eight sets of incoming YPbPr component video and analog/digital audio signals to any or all of the four outputs. Each input and output has YPbPr component video, L/R analog audio (balanced/unbalanced), and digital audio on coax (S/PDIF).
Video resolution up to 1920x1080@60Hz is supported with no degradation – guaranteed. An LCD on the front panel indicates the current connections. The VEEMUX-A can be controlled by four methods: Front Panel LCD with Keypad, RS232 interface, Ethernet, or optional Infrared Remote. The SM-8X4-HDA is the ideal solution for many applications, such as mission critical command centers, sports facilities and entertainment venues.
Features
• Supports High Definition and Standard Definition YPbPr component video, S-Video or composite video.
• Audio can be unbalanced analog stereo, balanced analog stereo or digital S/PDIF.
• Supports S/PDIF, DTS Digital Surround™, and Dolby Digital™ 5.1 digital signals.
• Supports 480i (interlaced), 480p (progressive), 720i, 720p, 1080i, and 1080p formats.
• Features break-away audio- allowing audio to be switched independent of video.
• Equipped with volume control: -80dB to 10dB, in 1dB steps.
• Control the switch through Ethernet, RS232, front panel buttons or optional IR remote.
Optional Feature
• Infrared Control (see page 32)- to order, add "IR" to the part number (i.e. SM-8X4-HDA-IR)

INSTALLATION
Connect the Sources
1. Turn OFF power to all video sources (inputs) that will be connected to the VEEMUX-A before connecting or
disconnecting any cables.
2. Connect each video source to the VEEMUX-A using 4CEXT-xx BNC cables. The groups of terminals are labeled INPUT1-8. and colored cables attach to terminals as follows: green (Y), blue (Pb) and red (Pr). If necessary, use BNC to RCA adapters to connect the cables to the video sources (see Fig. 1). If the cables used do not have BNC connectors on them but have RCA connectors instead, use an RCA-to-BNC adapter on each to connect to the VEEMUX-A.

• Infrared Remote (optional)
Every unit comes standard with the Front Panel LCD with Keypad, RS232, and Ethernet connection built-in. If desired, the Infrared option must be requested at the time of the order. The Infrared option requires the purchase of a separate remote control device (Infrared transmitter) as well as an Infrared receiver to be installed in the VEEMUX-A. No software is involved (see Infrared Control on page 32). With the RS232 option, there are no external devices to be purchased. NTI provides software commands as well as a test program to ensure the RS232 functions properly (see page 13 – RS232 Control).
Front Panel LCD with Keypad Control
The front panel LCD and keypad allow the user to monitor switch status and route any display to any video source on the switch. When the unit is powered up, each monitor is automatically connected to the video source of its equal number (i.e. monitor 1 to source 1, monitor 2 to source 2, monitor 3 to source 3, etc.). Along with the routing of the inputs (video sources) to the outputs (monitors) the keypad and LCD allow the users to configure the RS232 control interface. The keypad buttons perform the following functions.
ESC Escape back to the main display.

Volume Control
The volume level can be adjusted on each output port.
• To increment <▲> or decrement <▼> the volume, use the following command: <OUT>, <▼>, Double digit output port number, <▲> increment or <▼> decrement, <ENTER>
Ex 1: <OUT> <▼> 03 <▲> <▲> <▲> <ENTER>
This will increment the volume by +3dB (1dB/ step).
Ex 2: <OUT> <▼> 14 <▼> <▼> <ENTER>
This will decrement the volume by -2dB.
• To Mute, use the command: <OUT>, <▼>, Double digit output port number, the <0> key, <ENTER>
Ex: <OUT> <▼> 03 0 <ENTER> This will mute output 3
• To Un-mute, use the instruction: <OUT>, <▼>, Double digit output port number, the <1> key, <ENTER>
Ex: <OUT> <▼> 03 1 <ENTER> This will un-mute output 3
Memory Functions
There are 100 memory locations(0-99) available to save connection configurations. Location 0 is the power-ON default).
• Saving Connections To save all current connections, use the following command: <*>, <OUT>, Memory location, <ENTER> Ex: <*> <OUT> 5 <ENTER>
• Restoring Connections To restore connections from memory, use the following command: <*>, <IN>, Memory location, <ENTER> Ex: <*> <IN> 5 <ENTER>
Note: If the current switch configuration includes assigned Scan Mode dwell time values (pg. 9), to save the current configuration be sure to assign a memory location to it. Otherwise, when the VEEMUX-A is powered OFF, all dwell time values will be erased. Also, saving the configuration as memory location 0 will cause it to be the power-ON default configuration.
Configurations that are saved into memory locations via the keypad can be recalled via the web interface (page 23) and vice versa.
Menu Button
The Menu button is used to configure the RS232 port.
• The baud rate is selected from the “Baud Rate Menu” . To access this menu, use the command: <MENU>, the <1> key
Next, press the keypad number corresponding with the desired baud rate: <1> – 9600 <2> – 4800 <3> – 2400 <4> – 1200
Ex: <MENU> 1 1 This will select 9600 baud
• To set the switch address, use the following instruction: <MENU>, the <2> key, Double digit address (from 01 to 15- the default address is 01)
Ex: <MENU> 2 03 This will set the address at 03

NTI AUDIO/HD VIDEO MATRIX SWITCH
Scan Mode
Scan Mode causes output ports (audio and video) to automatically switch from one audio and video input port to the next consecutive audio and video input port after a specified period of time (referred to as the dwell time). Audio and video port switching will continue indefinitely and no ports will be skipped, whether there are audio or video sources connected to them or not. If desired, the VEEMUX-A can be configured to skip the scanning of specific ports using the RS232 Command Protocol (page 11) or Telnet (page 14) .
Dwell time settings can be any value from 0 seconds (000) to 255 seconds. A setting of 000 seconds (the default setting) disables Scan Mode for that output port. If Scan Mode is disabled for a specific port number, then the video or audio to that output port number will only change as decided by the administrator.
Note: While Scan Mode is enabled, audio and video ports of the same number will switch together. Independent control of video and audio ports will be disabled. I.e., when video output 1 switches from input 1 to input 2, audio output 1 will also switch from input 1 to input 2.
To configure Scan Mode from the front panel LCD
Press MENU, the following lines will be displayed:
1) Set Baud Rate
2) Set Unit Addr
Press MENU again, the following line will be displayed:
3) Set Scan Mode
Press 3 to select that menu item. The following request will be displayed:
Select Port
Select the output to be programmed using the numeric keys, then press ENTER. The display will show the current Dwell Time value for that output and ask for a new value.
Current Time: 16 New Time:
Using the numeric keys, enter a value between 0 and 255 and press ENTER. Leading zeros are allowed (000) but the number should not exceed 3 digits. The Scan Mode dwell setting value 0 will disable Scan Mode for that output port.
Scan Mode dwell time settings can also be configured through the RS232 Command Protocol (page 11), Telnet commands (page
14), or through the Web Interface (page 27).
NOTE: Scan Mode configuration settings can only be saved if they are assigned a memory location via the Keypad Control (page 8). Otherwise when the power is cycled to the VEEMUX-A, all Scan Mode settings will be erased.
TIP: If the Scan mode settings are stored as memory location 0, they will be loaded each time the VEEMUX-A is powered ON.
:
NOTE: If Outputs Scanning Sequences (page 27) Is enabled, Scan Mode as configured at the LCD front panel will be disabled.
The disabled front panel Scan Mode feature will be indicated by the message “SCAN SEQUENCE IS ACTIVE” on the LCD display.

RS232 CONTROL
RS232 enables the VEEMUX to be remotely controlled via RS232. To control the VEEMUX via RS232 the user has three options:
• write a program that runs on a PC using the Command Protocol (page 11)
• use the Matrix Switcher's Control Program (page 13) provided on the CD
• use the SerTest program (page 13) provided on the CD
Remote Connection
The RS232 Interface is designed to control the switch via serial (RS232) daisy chain connection from any host computer or other controller with an RS232 communications port.
The pin outs for the DB-9 connector on the unit are as follows:
RS232 Connector (DB-9 FEMALE)
PIN SIGNAL FUNCTION
1
None no connection
2 TXD Transmit Data (RXD at host) 3 RXD Receive Data (TXD at host) 4 DSR Data Set Ready 5 GND Signal Ground 6 DTR Data Terminal Ready 7 CTS Clear to Send 8 RTS Request to Send 9
none no connection
On the DB-9 female connector, pins 4 (DSR) and 6 (DTR) are shorted and pins 7 (CTS) and 8 (RTS) are shorted. Therefore, host handshaking is bypassed and TXD and RXD are the only active signals. A straight through DB-9 cable (not null modem) will work for most CPUs. To daisy chain multiple units, use NTI Matrix-Y-1 "Y" cables, except for the last unit connected. (see Fig 6). For a pinout of the Matrix-Y-1 cable, see page 40. For straight through cable pinouts applicable to various terminal types, see page
39.
Baud Rate
The unit powers up with a default baud rate of 9600 and a fixed data protocol of 8 data bits, no parity and 1 stop bit. The baud rate can be changed by pressing the MENU button on the front panel keypad. Then select 1 for SET BAUD RATE and select the desired baud rate of 9600, 2400, 1200 or 300. A data protocol of 8 data bits, no parity, and 1 stop bit is used for communications.
Unit Address
To allow multiple units to be controlled from a single CPU port, the RS232 control interface is designed to allow "daisy chaining" up to 15 units using the NTI Matrix-Y-1 "Y" cables (sold separately- pin out is on page 40). By setting the appropriate unit address with the keypad, each unit can be given a unique address (1-15). Then the unit will only respond to commands on the bus if its address is embedded in the command. To set the unit address select MENU on the front panel keypad. Then select 2 for SET UNIT ADDRESS and then type the address number (1-15) and (ENTER).

Autostatus
When Autostatus is enabled, any output-to-input connection change in the VEEMUX-A will cause an Autostatus message to be sent via RS232 to the administrator. The format of the message would be "pc SW,OP:IP<CR>"
Example of an Autostatus message:
pc 01,01:04<CR>
which means "At the switch with unit address 01, the output (01) has changed connection to input 04."
Notes: Message to the administrator will be delayed by any RS232 traffic being received by the switch from the administrator. Autostatus must be disabled before using SerTest or the Matrix Switcher's Control Program (page 13).
By default, Autostatus is disabled and must be manually enabled. Autostatus is also disabled any time the power to the VEEMUX-A is interrupted.

ETHERNET CONTROL
Telnet Interface-Port 2000
The Telnet Interface enables the user to control the switch using telnet client through an Ethernet connection. The telnet server listens on ports 2000 and 2005. Port 2000 is for an operator telnet session while port 2005 (must be enabled) is intended for a software control type session (see page 16). For operator telnet control using the telnet interface and the current IP address, type the following in a command shell:
telnet 192.168.1.30 2000
The VEEMUX-A will prompt the user for a password. The user must enter the password followed by <Enter>.
The factory default password is "admin".
With a proper password sent the VEEMUX-A will respond with:

Outputs Scanning Sequences
Figure 16- Web interface Scan Mode page
The Outputs Scanning Sequences page displays the configuration of an automatic switching sequence from input (video source) to input for each output (monitor).
The page displays:
output number being configured  the Scanning Sequence function status for that output  the Scan Mode status of each input (ON/OFF)  the length of time in seconds (dwell time) that each input will be viewed when connected
27
Page 32
NTI AUDIO/HD VIDEO MATRIX SWITCH
The output selection at the top of the page can be changed to any output to display the Scan Sequence Input selections and dwell times for that output.
The inputs and the amount of time that each will be viewed (0-32000 seconds) can be set to cycle sequentially for each connected output. If an input is set to 0 seconds, the sequence status will display “OFF”, and the input will be omitted from the scanning sequence. To include an input in the sequence, enter a dwell time period from 1-32000 seconds, and press Apply.
To quickly clear all dwell time settings, press the Clear All button at the bottom of the page. All sequence settings will change to “OFF” and all dwell time settings will change to 0.
To enable the scanning sequence for the output shown, place a checkmark in the “Sequence Enable” block.
Tip: To quickly enable the scan sequence for multiple outputs, use the “Sequence Enable” blocks found on the Switch Page (page 23).
Note: If only 1 input is set to Sequence “ON”, then the output connection to that input will not change when the Scanning Sequence is enabled.
Note: If the scanning sequence for an output is enabled through the web interface, then the Scan Mode for that output
as configured through the LCD menu (page 9) will be disabled.
Example of using Outputs Scanning Sequences
Problem: A synchronous scan is desired for all outputs with a dwell time of 30 minutes per input, and no two outputs should be
looking at the same input at any given time.
Solution:
1. Set the dwell time for all inputs listed in each output at 180 seconds (30 minutes). Press “Apply”.
2. Go to the Video Switch page (page 23) and set each output to an input of the same number (1 to 1, 2 to 2, 3 to 3, etc..). Click on “Submit” at the bottom of the Video Switch Page to submit selections and establish a connection and starting point for the scanning sequence. (Blocks shown in yellow in the third image indicate connections made.)
3. Click on the “Sequence Enable” box for each output (from the Video Switch Page).
4. Click on “Submit” again to begin the scanning sequence for each output.
From the moment the configuration is submitted, a synchronous scan will begin on all outputs. Each output will connect to its respective input for 30 minutes. After 30 minutes, the outputs will each switch to the next consecutive input and remain connected for 30 minutes. This cycle will continue indefinitely until sequencing is disabled.
Step 1- setup dwell times
Step 4- Click on “Submit” to begin
Step 2- setup starting point for scan and click “Submit”
Step 3- enable the scanning sequence

NTI AUDIO/HD VIDEO MATRIX SWITCH
How To Use The IRT
The IRT-64X32 enables the user to control the connections of up to 32 input ports and 16 output ports on up to four (4) separate NTI video matrix switches. When any key is pressed, the IRT will power ON. A number key should always be pressed first unless a change to the configuration is desired (see "Set Configuration" on page 35). When a number key is pressed the LCD will display that number blinking. What to press next depends on what action is desired;
• change the switch to be controlled
• change the output port
• change the input port
Note: The user must always change or confirm the output port first and the input port second
If the "SYS", "IN" or "OUT" key is pressed first, the LCD will display the current switch followed by the decimal point and an error signal "EE". The error signal will display because there is no number to be displayed. A number key must always be pressed before a "SYS", "IN" or "OUT" key is pressed.
Exception: The "SYS" key is pressed first when setting the configuration. (See page 35)
Power ON with SYS, IN or OUT keys Power ON with "2" key
Change the Switch
Press the number of the switch to be controlled. The number selected will be blinking in the last digit.
FYI: If the user realizes that an invalid number has been introduced before buttons, a correction can be made by pressing the correct number. If the correct number is a single digit, it must be preceded by a "0" to make the correction.
Press the "SYS" key. The blinking number will become blank and the switch number will update.
Note: If the number entered is larger than 4, when the "SYS" key is pressed the LCD will display the current switch and the error signal "EE".

Change Output Port
Press the desired port number. If there is no change in the desired output port, the output port must still be selected. As the digits are selected, the last number entered will blink. The LCD will also display the current switch number followed by the decimal point.
With the desired port number selected, point the IRT at the switch/receiver and press the "OUT" button to transmit the selection and make the change. The blinking number in the LCD will stop blinking. An LED on the receiver will illuminate.
FYI: If the switch did not receive the data the LED will not illuminate. The user can re-send the same data by pressing the "OUT" button again. The LED at the receiver will illuminate to indicate a completed transmission from the IRT..
Note: If the number introduced is larger than the maximum number of outputs the IRT is configured for, then once the "OUT" key is pressed the LCD will display the current switch and the error signal "EE".
Change Input Port
Press the desired port number. As the digits are selected, the last number entered will blink. The LCD will also display the current switch number followed by the decimal point.
With the desired port number selected, point the IRT at the switch/receiver and press the "IN" button to transmit the selection and make the change. The blinking number in the LCD will stop blinking. The LED at the receiver will go OFF.
FYI: If the switch did not receive the data the LED will not go OFF. The user can re-send the same data by pressing the "IN" button again. The illuminated LED on the receiver will go OFF when the received data is complete.
Note: If the number introduced is larger than the maximum number of inputs that the IRT is configured to control, then once the "IN" key is pressed the LCD will display the current switch and the error signal "EE".

Set Configuration
The IRT-64x32 factory default setting is 32 inputs and 16 outputs. When the batteries are changed the setting will return to the default value. At the default setting the IRT has the ability control any matrix switch with up to 32 inputs and 16 outputs without changing the configuration. However, when controlling smaller switches without changing the configuration it is up to the user to press valid number(s). To avoid confusion, it is recommended to configure the IRT to communicate with the largest switch to be controlled.
To change the maximum number of inputs or outputs:
1. From power-down state (blank LCD) press and hold the "SYS" button for at least 3 seconds. The LCD will first display an
error message but after 3 seconds the letter "c" will display:
2. Enter the number of inputs or outputs. As the digits are entered, they will be displayed and the last one entered will blink.
Note: Only the inputs OR the outputs may be configured each time the configuration function is used. To perform another configuration operation the user must start again at "Set Configuration" step 1.
3. Accept the choice by pressing the "IN" button for setting inputs, or the "OUT" button for setting the outputs. The LCD will not
blink anymore and will display “i” (for inputs) or "o" (for outputs) and the number.
Notes:
- The maximum number of inputs and outputs that can be entered is 32 and 16 respectively. If the user introduces a
number larger, the display will show an error signal ("c.EE") and the maximum number will remain at the last valid value configured.
- If more than one switch is being controlled, the IRT should be configured for the largest switch. It is up to the user
to introduce valid numbers to the smaller switches when making selections.

Battery Replacement
The IRT has a low-battery indicator to let the user know when it is time to change the batteries. The right-hand decimal point in the LCD display will illuminate (see illustration below). This will stay illuminated while the IRT is in use until the batteries are changed or the battery charge is too low for the IRT to operate.
To Change The Batteries:
1. Remove slide cover on rear of unit.
2. Remove old batteries carefully.
3. Insert (2) new “AA” cell batteries.
4. Replace slide cover on unit.
